Anchor-SAM: Active Mining of Latent Anchors From SAM Encoder for Road Extraction (opens in new tab)

Road extraction in high-resolution remote sensing imagery remains a persistent challenge due to occlusions and complex backgrounds, which lead to fragmented road topologies. However, existing road extraction methods constrained by limited pretraining remote sensing data often lack the generalization capability to distinguish roads from complex backgrounds. To address this issue, we propose Anchor-SAM, a novel framework that actively mines latent semantic anchors embedded in the SAM encoder to...
